Abstract

The invention discloses a transformer substation worker workplace noise analysis method, which comprises the following steps of 1) basic data collection; 2) physical model building; 3) work point noise value calculation; 4) exposure limit judgment; and 5) work point occupational sanitation evaluation. The method has the advantages that the influence on the noise attenuation caused by the geometric divergence of the noise propagation, and atmosphere, ground, buildings, green belts and the like in the propagation path can be accurately considered, so the noise intensity of any work points in a transformer and the peripheral space of the transformer can be accurately predicated, references are provided for the transformer substation worker workplace noise sanitation evaluation, and the monitoring and the evaluation of the transformer substation noise occupational sanitation can be effectively assisted. Meanwhile, the invention also provides a transformer substation worker workplace noise analysis system.

Description

technical field [0001] The invention relates to the field of occupational health evaluation of noise working environment, in particular to a method for analyzing noise in workplaces of transformer substation workers, and also relates to a noise analysis system for workplaces of transformer substation workers. Background technique [0002] The noise in the substation mainly comes from the noise equipment of transformers, reactors and fans. In order to ensure the safe operation of power equipment, electric power workers often work in substations, including inspections, tests or maintenance, especially when they work for a long time near high-noise equipment such as transformers. These noises may have a certain impact on the physical health of power workers. hazards. Therefore, it is of great practical significance to carry out the prediction analysis and evaluation of the noise in the workplace of substation workers, strengthen the labor protection of power workers, and promo...
